The more general case when E is a

topological vector space will be presented in Remark 2.

Therefore this space is a

topological vector space.

Let E be a

topological vector space and B an absolutely convex, closed and bounded, subset of E.

Let E be a normal

topological vector space, Y a

topological vector space, U an open subset of E, L : dom L [subset or equal to] E [PHI] Y a linear single valued map and T [member of] [H.

Let X be a nonempty subset of a

topological vector space and f: X x X [right arrow] R be a function with f{x, x) [greater than or equal to] 0 for all x [member ] X.

Let X be a

topological vector space and T : X [right arrow] X an operator.

They write for students who are familiar with general topology and linear algebra, but not

topological vector spaces.
